Prosecutors will not seek leave to appeal to the High Court on the acquittal of Lloyd Rayney

Prosecutors have announced they will not be seeking to further appeal against the decision to acquit Lloyd Rayney of the murder of his wife.

Last month prosecutors failed in an appeal against a judge's decision last year to find Mr Rayney not guilty of the murder of his wife Corryn, 44, in 2007.

Mrs Rayney disappeared after a bootscooting class in Bentley and her body was found more than a week later in Kings Park.

The trial judge found the case against Mr Rayney lacked crucial evidence, and the three appeal judges upheld his ruling.

Prosecutors could have tried to take their case to the High Court but in a statement today said they would not be making that step and no further comment would be made.

Mr Rayney's only comment was to ask what would happen to the officers involved in the case.

"What will happen to the police the trial judge said gave misleading evidence, pressured a forensic pathologist to change his report, abused their position of authority and behaved reprehensibly? " he said.

Mr Rayney is still facing charges of bugging his wife's telephone.

He is also suing the State of WA for defamation over police naming him as the prime suspect over his wife's disappearance.

In a statement, a WA Police spokeswoman said today's decision was not a matter for comment from police.

"Allegations arising out of the trial were referred to the Corruption and Crime Commission and WA Police understands some of the matters remain under investigation."

"As such, WA Police is not in a position to comment further at this time."

The statement said the unresolved murder case of Mrs Rayney remains open.
